This invention relates to a suction -comb adapted for use in the cleaning of cows. horsesand other animals, and constitutes an improvement to a similar device shown and described in my coending application Seriall No. 320,607, file November 20, 1928.

The device com rises a comb which 1s adapted to sleek t e animals coat end at the same time loosen any dirt or scurf which may be imbedded in the hair, the suctlon n ozzle, which is combined with the comb, ac tlng to carry the foreign matter away immedlately and thereby prevent its resettling on the animal.

It will be understood that the suction nozzle is adapted to be coupled to any suitable for-m of vacuum producing apparatus for i creating the desired suction in the nozzle around the comb.

The object of the present inventlon 1s to construct the comb in such a. manner that it will be equally effective as it is moved inI either a forward or a backward stroke over an animals hide and at the same time prevent the loose halr from becoming entangled in the comb, obviating the clogging of the nozzle. v

Referring to the drawings:

Fig. 1 is a longitudinal sectional elevation of the device taken on the line 1-1, Fig. 2 5

Fig. 2 is a transverse sectional elevation taken on the line 2-2, Fig. 1;

Fig. 3 is an inverted plan View;

Figs. 4: and 5'are vlews similar to Figs. 1 and 2 respectively, showin one modified form of the invention, Fig. 5 eing a section on the line 5 5, Fig. 4, and

Figs. 6 and 7, 8 and 9, 10 and 11, and 12 and 13, illustrate other modied forms within the scope of the invention.

The device, as shown in Figs. 1, 2 and 3, comprises a suction nozzle 1, which consists of an elongated hollow body portion 2, which is shaped 1n a manner to comfortably fit the hollow of the hand of an operator, by gracefully curving u wardl from the mouth of the nozzle and inward y from the opposite ends thereof toward its center, where the said hollow body portion is provided with a substantially cyhndrical hollow extension 1929. Serial No. 372,12..

3, which projects from one side of the said body portion and conforms to the lateral curvature of the body portion of the nozzle.

The res ctive side walls'4.- 'and 5-of the hollow bo y portion 1 are spaced apart to form the elongated mouth or opening 6 of the nozzle, in which is located the comb 7.

The comb 7 comprises a solid portion or lback bar 8 which is located within the o nmg 6 of the bodly portion 2 and is spaced a ve and substantia l parallel to the bottom edge 9 of the said bo y portion 2.

The teeth 10 of the or outside the bottom edge 9 of the body portion 2 of the suction nozzle 1.

As shown in Fi 1, 2 and 3, the back bar 8 1s formed integra with and extends between the end walls 11, 11 of the body 2, and is disposed 1n and extends through the mouth 6 of the nozzle substantially at the center thereof.

The teeth 10 are divided into two separate series, the teeth of the series being respect1vely disposed in sta gered relation with respect to each other along the op osite sides 1 4 and 15 of the back bar 8, and) the o positely disposed outside edges 16 and 1 of the teeth 10, 10 flare downwardly in opposite directions toward the adjacent side walls 4 and 5 of the nozzle.

The lower face 13 of the back bar 8 is sub- MONTGOMERY COUNTY,

comb7 project from il Ithe back bar 8 of the comb to a point below stantially dat and forms the base of the spaces between the teeth 10, 10. The inner edges 19' and 20 of the teeth 10, 10 are in divergent relation to the outer edges 16 and 17 respectively of said teeth, and extend from the ends gf the teeth to the base surface 13 of the back ar 8. This face 13is of such awidth that the hairs, loosened by the teeth 10 and drawn into the nozzle between either of the adjacent pairs of the side walls 4 and 14, or 5 and 15, cannot straddle the back` bar 8 and thereby remain on the surface 13 thereof, to clog the nozzle, but a greater portion of the length of any single hair will extend into the space between either one or the other of the said pairs of adjacent walls and, therefore, will be drawn into the nozzle.

' backward stroke with equal bar 8 by rll`he back edge 18 of the back bar 8 is relatively sharp and is formed by the side walls 14 and 15 thereoie converging, which produces stream lines for the passage of the air and obviates the possibilities of any eddies or air pockets being formed within the nozzle, which would tend to retard the carrying away of the loose hairs and scuri.

The device shown in Figs. l and 2 is articularl adapted for use with animals W ich are she ding their hair and for animals having relatively long hair, the spacing of the ,teeth being comparatively wide so as not to present excessive retardation to a. large amount of loose hair passing into the nozzle and at the same time bein suiciently close together to separate the hair so that the loose hairs and scurf can be readily removed from the animals coat.

The device shown in Figs. 4 and 5 is adapted for use with `animals which have comparatively short hair, or those which are not shedding, such conditions permittin the teeth to be placed closer together an in a single row, however, like the device shown in Figs. l, 2 and 3, the oppositely disposed edges 16a and 17 a of the teeth 10a are divergent.

This divergency of the opposite edges of the teeth of the comb permits the comb to be moved over the hide in either a forward or a effectiveness, the angularity of the edges of the teeth permitting the teeth to move easily over the hide without rolling the hide into wrinkles, which would irritate the animal and cause it to become restless and hard to clean, and at the same time the teeth will penetrate the mass of hair, separating the hair and loosening any scuri or dirt adhering to the skin, so that such foreign matter and loose hair can be readily carried oi by the suction created in the nozzle.

As shown in Figs. 4 and 5, the back bar 8a is substantiall elliptical in cross-section, the sides 14a and 15a being curved toward each other and the opposite y disposed edges 13a and 18a formed thereby being relatively sharp to present the stream line effect above noted.

As shown in Fig. 4, the ed es 13a and 18a are disposed in a plane exten ing at an angle across the mouth of the nozzle above the bottom face 9a of the nozzle, and this angularity and the sharp edge 13a of the bar 8a combine to discourage the straddling of the the loose hairs due to the point 13a the wall 4a of the nozzle than being closer to to the wall 5a thereof, causing currents of air passing into the nozzle to circulate around the edge 13a and thereby carry of any hair which would tend to adhere thereto.

The back bar 8a, like the back bar 8, is formed integral with and extends between the end walls 11a, 11a of the nozzle 1a.

In the devices shown in Figs. 6 and 7, and

negaron 8 and 9, respectively, the combs 7b and 7c are formed in substantially the same manner as the comb 7 shown in Figs. 1, 2 and 3, with the exception that these latter combs are movable relative to the nozzle in a plane substantially perpendicular to the faces 9b and 9c of the nozzles 1b and 10 respectively.

In Figs. 6 and 7, the back bar 8b is formed integral with and extends between the end walls 11b, 11b of the nozzle 1b and the walls 13b, 14?; and 15b combine to form an elongated channel member on which the teeth 10b are formed, thewalls 14?) and 15b extending upwardly along and being slidable with respect to the sides of the back bar 8b.

The back bar 8b is provided with cavities 20, 20a, in which are springs 21, 21a, which tend to force the comb 7b out of the nozzle 1b, this movement being limited by screws 22, 22 slidably mounted in the cavities 20a, 20a, and in apertures 23, 23, formed in enlargements 24, 24 formed in the opposite ends of the nozzle 1b.

By adjusting the screws 22, 22, the distance which the ends of the teeth 10b, 10b extends beyond the Surface 9b of the nozzle may be minutely controlled to suit the requirements or ideas of the operator.

In Figs. 8 and 9, the comb 7 c is likewise movable with respect to the nozzle 1c in a plane substantially perpendicular to the face 9c, and for this purpose the back bar 8c of the nozzle is hollow as indicated at 25 for the accommodation of a supplemental bar 26 which extends between and is secured to the end walls llc, 11o of the nozzle 1c by screws 27, 27, springs 210, 210 located in cavities 200, 20c formed in the su plemental bar 26 tending to force the comb lo outwardly from the nozzle 1c.

In Figs. 10 and 11, the back bar 8d is of lesser width than the widest portion of the teeth 10d and the edges of the teeth 10d flare outwardly for the purposes noted and the back bar 8d is rigidly secured vto the end walls in any suita le manner, such for example as slotting the said end walls and forcing the ends of the comb 7d into the slots.

n Figs. 12 and 13, the teeth 10e are formed integral with one of the side walls of the nozzle, for example the side wall 15e.

From the above, it will be noted that in each case the opposite edges of the teeth are disposed at angles extending in opposite directions with respect to each other and with respect to a plane disposed perpendicular to the plane of the mouth of the nozzle so that regardless of whether the comb is b'ein moved through a forward or a backwar y stroke, the teeth will present an angular surface to the hide which will obviatel the wrinkling thereof under the comb.

The corners of the teeth as shown in the several views of the drawings are slightly rounded so that there will be no tendency for lll of the' device shown in Fig. 1, are spaced a sufficient distance from the comb. 7, and the teeth of the comb project such a relatively slight distance below the face 9 of the nozzle, that it will be impossible'for the comb to be 10 tilted to such an extent that the ed es of the teeth would be presented to the hide of an animal in a position perpendicular to the hide ofl the animal being cleaned, thereby obviating such a condition, which would result in the skin being wrinkled under the teeth of the comb. To this end the angle of ilare of the edges of the teeth is eat enough with respect to the plane of l e surface 9 that even in the maximum tilt permitted wherein the bottom ed e of one or the other of the walls 14 or 15 0% which the surface 9 is formed is in contact with the hide and the ends of the teeth 10 are also in contact with the hide, the said edges of the teeth will be resented at an angle other than 90 to the hi e.

The tendency of the ed es 19 and 20 relative to the face 13 of the ack bar 8 permits the comb to free itself of any loose hairs which ma have assumed positions parallel to the bac bar and lying across a number of the teeth, in which case the hairs of the animals coat which are not loosel will act as a brush to brush the said loose hairs out over the ends of the teeth 10, whereupon such loose hairs will be drawn into the nozzle between the outer edge of the teeth and the adjacent side wall of the nozzle.

In the form of the device shown in Figs. 1, 2 and 3, the inner edges 19 and 20 of the teeth 10 are beveled as indicated at 30 so that these edges, the pitch of which is relatively slight with respect to the lane of the mouth of the nozzle, will not ri e up on the hair and lift the working edge 16 or 17, as the case may be, from out of the hair on the backward and forward strokes of the device over the animals coat. The bevelin of the sides of the teeth in the manner in icated at 30 causes the edges 19 and 20 to assume a relatively sharp edge which will plow through the hair rather than ride over the same.
